I am currently placing aprox. 95 to 100 1206 size ferrite beads onto a pcb and having difficulty solding these parts. They appear to be soldered when the board comes off the reflow, but you can flic the parts off by hand. We thought they were contami

Hi Pat, is the soldering Ok when you solder them by hand ? We use some larger ferrite beads with no problems in reflow but I must say that we use a vapour phase and only max 5 parts/PCB. They do have a high thermal capacity and you use a lot of them,

Pat: No, but if you describe the situation we may be able to sort through your soldering problem. Good luck. Dave F

We are having a lot of tomb stoning with this no clean solder paste. It's limited to larger, complex boards, affecting 0603 ferrite beads, capacitors and SOT23s. It was suggested that paste removed from a stencil should not be put back in it's origin

Thanks for the reply, how do people handle different packages then if you can't add new ones? If we had a 1206 sized inductor, then a 1206 sized ferrite bead and so on, they would all have to be grouped under the same generic heading? e.g. Chip-R321

Hi, There are 2 main steps to reducing EMI from a product. The first is to minimise it at source with smart design (keeping signal traces short, lots of decoupling etc). There should be design guides available from internet seach engines. Many ma

| Anyone using SMT "Fair-Rite" beads? We have a P/N 2743019447 that we're using. We need to know the shear force strength of the part and the vendor's man who knows is in Deutschland and can't help until Monday. I can't wait that long. | | Also, do
